The rumor mill is in overdrive this week, and "Extra"
has the latest news on all your favorite stars. Today,
it's a special superstar edition of Rumor Control, devoted
to Brad Pitt, Jennifer Aniston and Paris Hilton.

Brad Pitt already has one "Mrs.
Smith" on the big screen, but is it true that his
soon-to-be ex-wife, Jennifer Aniston,
is also calling herself Mrs. Smith?

Yes -- according to Inside TV magazine. Aniston, who
is in Chicago shooting "The Breakup," checked
into The Peninsula Hotel under the alias name, Mrs.
Smith. The magazine reported she gets a kick out of
the staff calling her that.

But that's not the only Brad and Jen rumor making headlines.
Next up: is Hollywood's once-golden couple breaking
up all over again?

Yes -- Pitt is taking his production company, Plan B,
to a new studio -- and he's not taking Jennifer with
him. She'll remain involved in some projects, which
are already in the works.

Yes -- Paris and Paris partied at the home decorated
by Esquire magazine and formerly owned by football star
Keyshawn Johnson. And Hilton loved the house so much
that her new fiancé, Paris, laid out a cool $12
million for the property.

And finally, while Paris was partying at mansions, did
her prized pooch Tinkerbell bite a "Today"
show producer when Kathy Hilton was
on with Anne Curry?

No -- "She probably just kind of 'grrr,'"
Kathy insisted. And the producer now says it was more
like a scrape than a bite.
